What you need:
A card base
Panel the same size as card front.
Stamp positioner or MISTI stamp tool
Stamp your chosen image on your card base and again on a panel the same size as your card base. Use a stamp positioner or a MISTI stamp tool to make sure that both images are positioned in the same place. Color both images exactly the same. Use a shape die to cut an aperture in the panel over the stamped image. Cut the panel 1/4" smaller than the card base. (1/8" on each side) Use dimensional tape to attach the panel so that the image on the aperture and the image on the card base line up. Glue a word die cut across the aperture.
